NEW YORK (AP) - The second time was not a charm, or a wedding ring, for Nicollette Sheridan and Michael Bolton. They won't be getting married. Sheridan's spokeswoman says Sheridan and Bolton have "amicably ended their engagement." They first started dating back in 1992 and broke up five years later. They got back together in 2005 and were engaged in 2006. Sheridan was married to Harry Hamlin from 1991 to 1993. Bolton ended his 15-year marriage to Maureen McGuire in 1990. Bolton and McGuire have three daughters together.
